Best of luck on your research. I imagined that FLC were informal groups of faculty members  who meet to explore topics of common interest on a regular basis.

Meilan:

Informal learning frequently takes place within Communities of Practice that emerg among faculty as well as professionals in organisations etc. Here's a link to a literature review on Communities of Practice that can inform your research:

Here's a link to the publications in ResearchGate regarding your topic: https://www.researchgate.net/publicliterature.PublicLiterature.search.html?type=keyword&search-keyword=informal+faculty+learning+community&search-abstract=&search-journal=&search=Search

Best wishes for every success with your research.

FLC are in fact, de facto, informal learning communities.... samples of which are the “brown bag meeting” or “peer sharing”...you could try to look into these...

Contact the office of faculty development on the CSU East Bay campus.  They do a host of faculty learning communities yearly.

Thank you all, Iman, Debra, Richard, and Doris for your valuable ideas and information.

You're welcome Meilan!

Best of luck on your research, Meilan.
